Yes, however there are other issues at hand when adding outboard equipment to an alarm that isn't intended for such purposes.......but I'm not diving into that discussion.
There's other functions going on when a AVS session are going on, and if the operator can't control the gain and level, adding the hardware is useless besides giving yourself the warm fuzzy feeling when listening in via your cell phone.
AVS isn't a static installation and monitoring situation, usually it works by having the session initiated by the CS operator after receiving the report from the digital communicator, by calling back the site, then listening in. The control generally mutes the audibles and keypads while the 2 way session is ongoing. Typically the operator will speak to the site via the onsite speakers and operate via a PTT sort of interface. If no response is gotten or verified, most trained operators will continue to listen in for a short period, adjusting gain or levels while listening in. A lot depends on the hardware and how well (or not) the CS operator was trained,.
I've got some pretty interesting audio files of actual alarm events captured on AVS and you can clearly hear when levels and gain are being adjusted....and I'm talking installations with ample coverage with mics and speakers.
